Title: Controller for vehicle generator
Inventor: SAKAI TAKESHI
IPC: F02D29/04
Filed: 1990-07-10
Abstract: PURPOSE:To suppress fluctuation of engine load due to connection/disconnection of hydraulic compressor load by limiting the generator output according to the load condition of the hydraulic compressor within a range where the sum of driving torque of the hydraulic compressor and the generator does not exceed a predetermined maximum allowable value. CONSTITUTION:A maximum field current Ifmax is searched from a table stored in a built-in ROM based on the increase of hydraulic load torque due to opening of a control valve 2. When the slip start torque Ts of a pulley 12 is constant, maximum allowable load torque Tsp to be applied on the pulley 12 is set at a constant value which is somewhat lower than Ts. Since the driving torque To is assumed to be constant, allowable maximum generator driving torque Temax is equal to (Tsp-To) which is a constant value. There is a predetermined correlation between the necessary torque and the field current If of an AC generator and the correlation is previously built in the ROM of an ECU 1 in the form of a table. Consequently, the allowable maximum field current Ifmax corresponding to the allowable maximum generator driving torque Temax is searched from the map.

Title: Thermal transfer recording method
Inventor: MAEKAWA SEIICHI
IPC: B41M5/382
Filed: 1985-08-21
Abstract: PURPOSE:To obtain an image excellent in weatherability, abrasion resistance, gloss and sharpness, by applying thermal transfer recording to a transparent image receiving sheet from the surface opposite to an observation surface by using a transfer sheet. CONSTITUTION:A transparent support is used as the support of an image receiving sheet and the surface opposite to an observation surface is set to an image receiving surface and a transfer sheet is superposed to perform thermal transfer recording. Because an image is formed to the surface opposite to the observation surface as mentioned above, a problem such that scratching is generated in melt transfer by friction is eliminated and the enhancement of sensitivity by the use of low m.p. ink becomes easy. In sublimation transfer, the fading and sublimation of a sublimable dye are prevented by the light blocking and shielding of the image by the transparent support and the weatherability of the image is enhanced. Further, by using the transparent support having the smooth observation surface, the gloss, sharpness and density of the image are enhanced and the water resistance and chemical resistance of the image are also enhanced.

Filed: 1980-12-24
Abstract: PURPOSE:To remove the parasitic capacity of a grid point section of a gate electrode of the mesh gate type FET by forming a foundation layer just under the grid point section in an inert layer. CONSTITUTION:An N type conductive layer 5 shaped onto a GaAs substrate 6 is removed selectively and an opening 11 is formed, and the semi-insulating substrate 6 is exposed in the bottom of the opening. The conductive layer 5 is  coated with a conductive material, and source electrodes 1 and drain electrodes  2 are shaped. The gate electrode 3 is molded to the bottom of the opening. Since the grid point section 3' of the gate electrode 3 is formed in the opening 11, the foundation layer can be shaped by not the conductive layer 5 but the semi-insulating layer 6, the inert layer. Accordingly, the parasitic capacity of the grid point section is removed.

Title: Semiconductor pressure detector
Inventor: TAKEUCHI TAKANOBU
IPC: H01L29/84
Filed: 1994-08-04
Abstract: PURPOSE:To obtain a semiconductor pressure detector which has no dispersion in the gage resistance value and has a high accuracy. CONSTITUTION:Crystal subboundaries 27 are generated when a recrystallized silicon film 23 is formed by a laser, and crystal defects are contained in the (100) direction. Metal wirings 51 such as aluminum, gold or the like are arranged onto the crystal subboundaries 27 crossing a gate resistor 3A. Currents flowing through the gate resistor formed by the recrystallized silicon film 23 are made to flow through the metal wirings 51 in the sections of the crystal subboundaries 27. Consequently, currents flowing through the gage resistor are difficult to be subject to the effect of the crystal defects. Accordingly, the effect of the crystal defects can be reduced, thus acquiring a semiconductor pressure detector having high accuracy and sensibility.

Title: Image pickup tube device and its driving method
Inventor: SATO KAZUHIRO
IPC: H01J31/28
Filed: 1985-08-23
Abstract: PURPOSE:To attain stable ABO operation even when capacity coupling exist between a grid electrode and a photoelectric conversion plane by applying a voltage signal corresponding to a signal current from a photo-conduction target on the second grid electrode. CONSTITUTION:The signal current is obtained by the scanning on a photoelectric conversion plane 11, and is converted to the voltage by a resistor 12, and after amplifying 20, it is overlapped on a bias voltage 16, and added on the second grid electrode 3. Thereby, the current value of a scanning beam is controlled automatically according to the change of the signal current. At such a case, at the amplifier 20, the polarities of the input and the output of each signal are inverted and also, the polarity of the signal added on the electrode 3 and that of the signal of the conversion plane 11 are reversed. Consequently, the voltage signal with positive polarity is added on the electrode 3 against the signal charge of negative polarity of the conversion plane 11 and even when the capacity coupling is generated, only a negative feedback circuit is formed, the stable ABO operation is performed.
